Throughout the year entrance doors are faced with keeping the elements out and in securing homes right across the UK. With composite doors now the main choice for discerning homeowners with over 50% share of the entrance door market, they are now under the most exacting scrutiny due to the large numbers of installations, each and every week.

By definition a composite door is made up of different materials and combined are designed to look good, with the promise of an extended life span well in excess of 10 years. We know that installation companies generally prefer the timber core based composite doors and the challenge for our segment of the market is to carefully manufacture these doors to withstand the harshest of conditions.

Water ingress has been a challenge for some, particularly to the foot of the door and in and around the glazing apertures. As this has been a known concern for many years it was for good reason that we introduced our unique Moisture Barrier System back in 2014 and subsequently, customer concerns plummeted overnight.

Glazing apertures in composite doors all have the potential for water ingress and suppliers have different ways in attempting to mitigate this potential hazard. It’s an additional production process for all of us and we’ve found that aluminium tape to the aperture along with a wet seal once the cassette is installed, is the ultimate failsafe standard. I would suggest that the provision of a wet seal on all glazing cassettes in all composite doors is the most prudent way forward, based on our experience in manufacturing dating back to 2002.

So surely as an industry we should be doing more to reduce product liabilities with a caring attitude to trade partners and with a duty of care ultimately to the end consumer? After all it’s our reputation on the line for the long-term.


Yours sincerely
